Ex 1.1, 6Rita goes 20 km towards east from a point A to the point B. From B, she moves 30 km towards west along the same road. If the distance towards east is represented by a positive integer then, how will you represent the distance travelled towards west? By which integer will you represent her final position from A?
Point A is O
Distance towards East is Positive
Distance towards West is negative
Given that,
She goes towards east 20 km to point B
And then,
She moves towards west 30 km.
So,
Final Position = 20 − 30
= −10
So, Final position is represented by a negative integer, –10
